W12×35 wide-flange beam

Detailing dimensions and section properties from the AISC Shapes Database, 16th Edition. Values are shown to the nearest 1/16 in. as they appear on a shop drawing.

W12×35 measures 12 1/2 in. deep with a 6 1/2 in. flange, on a 5/16 in. web and 1/2 in. flanges.

At 35 lb per foot it is one of the 29 W12 sizes, which run from 14 to 336 lb/ft.

For strong-axis bending its section modulus is Sx = 45.6 in³ and its moment of inertia Ix = 285 in⁴, with a plastic modulus Zx = 51.2 in³.
